Abstract
According to the present invention, highly accurate adjustment of the angles and positions of optical elements constituting an optical scanning unit can be easily performed. For a cylindrical lens that makes the light beam for exposing a photoreceptor converge on the surface of the photoreceptor, a frame is provided for holding the cylindrical lens therein. The frame is supported by two support portions for a chassis of the optical scanning unit such that the longitudinal direction of the cylindrical lens becomes parallel to the scanning direction of the photoreceptor. The optical scanning unit is configured such that the angle of the cylindrical lens in the longitudinal direction is adjustable in the sub-scanning direction of the photoreceptor at the support portion on the front side (operational side) of these support portions.
